Functional Description

The SCT-series TCXO combines Esterline Research and Design’s new patent-pending M-SAC compensation

technology with state-of-the-art oscillator designs to produce TCXOs that outperform many OCXO designs

for stability, warm-up time, and input power. The new SCT-series TCXO offers temperature performance

unmatched by any other TCXO on the market today and is offered in a small footprint, one-square-inch

hermetic package.

This product is compensated for trim effect to ensure the temperature stability performance is maintained

as the frequency is adjusted by the user to correct for aging (drift over time). Stability degradation result-

ing from frequency adjustment is virtually ignored by most manufacturers, and the M-SAC compensation

ensures the low-ppb temperature stability achieved by SCT-series TCXOs is maintained at frequency adjust-

ment extremes.
